My grandmother took me to church on Sunday all day long, every Sunday into the night. Then Monday evening was the missionary meeting. Tuesday evening was usher board meeting. Wednesday evening was prayer meeting. Thursday evening was visit the sick. Friday evening was choir practice. I mean, and at all those gatherings, we sang.
An Apostle is a missionary, bearing testimony of the reality and divinity of Jesus Christ in all the world.
I grew up going to a real small missionary baptist church. We would sing a lot of the old standards... the hymns and everything. Those songs are still my favorite and are pretty timeless.
The key to successful missionary work is a close relationship between the missionaries and the members. Creating an environment in working with members that will bring more into the Church.
Haven't two hundred years of failed missionary work overseas taught anybody anything? You can't convert people to anything - whether religion, or something as inane as our flicks.
